FOUNTAIN-PEN'.

To all whom t mayconccm:

-Be it known that I, Lili- JAN PLANCHER,

` a citizen of the United States of America,

fof which the following is a full, clear, and

-unattached to the barrel Aelement of the pen,

exact description.

.' Ihis inventiony relates to improvements in fountain-pens of the self-filling variety having a compressible ink-sack or reservoir One of the objects of my within the same. invention is to provide limproved means to compress the reservoir forthe purpose of filling the same withink, said means comprising a lever shiftably supported by but of the pen, the lever having Ian extension arranged to act upon the ink-sack. An advantageous feature of my invention is the fact that there are no pivot-pins or other means the lever to the barrel of the pen. Although the lever is arranged rfor radial movement, it isnot secured to but merely rests in contact with the barrel. Its novel formation permits it to be moved radially about a ful- Crum-point, which is not a pin, or equivalent support, such as heretofore found necessary to pivotally mount the levers pens. l

Another advantageous feature of my invention is the provision of novel means for releasably locking the lever in its normal closed position.

Other points of improvement will appear in the following detailed description, reference being had to the accompanying drawing, wherein- Figure 1 is a fragmentary sectional view, partly in elevation, of a pen embodying my improvements Fig. 2 is an enlarged cross-sectional view thereof, the section being taken on a line 2-2 in Fig. l;

required to secure the barrel or any other A in this type of `with the slot 21 (see Ythrough the slot and Patented Apr. 22, 1919.

Application iea Apn'i 17, isis. 'seriaiiraazaosz Figs. 7 and 8 are enlarged fragmentary sectional views of modified means for locking the lever in closed position.

Contrary to the usual practice, my improved lever is located eXteriorly of the barrel, that is to say, not mounted in a slot. The eXtension of the lever is the only portion which is not located exteriorly of the barreh To preclude any projections or raised portions, `the lever is preferably made to conform toan arc, the radius of which is Jche same as the radius of the outside diameter ofthe barrel; hence the lever lies close against the barrel. The extension of the lever passes through an opening in the barrel located adjacent one end of the lever. The other end of the lever carries a catch or fastening means to engage an adjacent opening in said barrel, whereby the lever can'be latched in closedposition.l It will be therefore'apparent that the barrel of the pen is provided with openings that do not communicate, and not with a slot.

y improved lever consists of a body portion 9 having an extension 10 at one end comprising a neck 11 and having an enlarged or relatively broad portion 12. The 4opposite end of the lever carries a catch 13 formed by bending said end to provide a projection having yieldable walls 14 and 15, and a latch 16. It will be seen that the neck 11 extends `away from the body portion in an angular direction and that vsaid neck is `somewhat narrower thanthe enlargementV `when said lever is raised at the end 23 (Fig.

1) to its full extent. A shoe or presser-bar 24 is provided which may be cemented to the sack or otherwise mounted so as to protect same from contact with the extension 10. I do not deem it essential to employ any particular form of presser-bar.

To assemble the pen, the lever will be positioned to cause the projection 10 to aline dotted lines, Fig. 5), after which the said projection will be passed moved to the left (in Fig. 2).

'Io fill the pen, the lever will be 4raised at the end 23, causing the projection 10 to coinpress the sack as indicated in Fig. 2V. "Ihe actionof compressing the sack will force the shoulders 17 .against the wall of the pen `(see In other words, as soon as the end 28 is lifted, the shoulders 17 will contact with the barrel `and thereafter constitute pivot points. When the leve-1' is released, the inflowing ink will expand the sack and fill the same. To lock the :lever in closed position,the latch 13 will enter the openino' 19 or a bushing 25 vin said opening (Fig. 8 As lthe Vlatch 13 consists o-f resilient members,

l width of the neck; hence,

.-pivotally mount Vthey will slightly yield when forced 1n the lopening Aor bushing; hence they will be placed under tension, Athereby firmly holding `the lever closed.

Instead of providing the catch 13, I may provide Athe lever (indicated by l26, Fig. 8) with 'a yieldable button-head 27 to yengage a :bushing 28 in the barrel 29 of the pen; or I may provide vthe barrel of the pen with a yieldable button 30 (Fig. 7 and the lever 31 with a recess 32 to engage'same.

lIt will be'apparent from the foregoing description that fno pivot pins are used :to the lever 9, fulcrumpoints being provided by the special construction of lever, as has been set forth. If desirable, the enlargement 12 may be provided with -teats 33 Ito engage channels 34 in :the presserbar 211, whereby said lever and said presserbar are maintained in operative alinement.

It may here be stated that the neck 11 of the extension 10 is slightly wider than the slot 21, but vthe length ofthe slot exceeds the after the said projection has been inserted :and turned, the lever cannot be fnioved longitudinally of the barrel to any great extent, lbut can be slightly shifted to cause the enlargement to accommodate itself to the presser-barL The pivotal engagement of the barrel and lever yis of a shiftable nature, for the reason that Vthe lever is not Vpositively fixed, but can shiftslightly,

geven after the fulcrum-points have been forced into vContact with `the barrel. What I claim as my invention is: 1. In a fountain pen, a barrel having two openings in longitudinal alinement with each other, in combi-nation with a sack contained in'said barrel, a flever [adapted to -lie mainly along the Aoutside of said barrel when not used and to be turned :into upright position for bearin onsaid lsack at wvill, one end of said .lever eing formed into a vspr'ingsnap to enter one of said openings and engage the edges thereof and the other end of said lever being bent "to enter the other opening and formed with a shoulder which provides a fulcruin .for said lever by engagement with the wall of the latter opening, the latter end of said lever being adapted to bear downward on said sack when said lever is turned into upright position.

2. In a fountain pen, openings in longitudinal alinement with each other, in combination with a sack contained in said barrel, a lever normally lying fiat against theoutside of said barrel, but adapted to be turned into upright position for compressing said sack, and :a ldevice interposed between said sack and the operating end of said lever and normally-covering most of the topof said sack, the said lever having a barrel having two apart adapted tosnap intoone oftheseopen-` Vturned :upright for compressing said sack, the

`operative end vof said lever being provided with ,a broadened part for actingion said sack .and a bent .narrower part connecting this broader part with 'the body of the lever, the width of said broader part -being lessthan the length lof-.said opening :and the width of said narrower part Vbeing less Vthan the width of said opening, he bent form of said narrower part providing a shou-lder as a fulerum substantially as-set forth.

i. In a fountain pen, a Sbarrel having an opening, in combination with a sack inclosed in said barrel landl a :lever loosely fulcrumed to said barrel in-orderthat at will it may be raisedtocompress said sack or folded fiat on the outside of said barrel, the said lever being provided with .a 4bent resilient .part for renterfi-ng saidfopening as a catch 'to hold said lever flat and with a terminal part extending beyond said ieatchonthe outside of the barrel for convenience in raising said lever.

5. In a fountain pen, a barrel rhaving Ytwo openings, incombination with a sack within said barrel and 4a lever having near one end a bent partentering oneof saidepenings and forming a shoulder which acts as a fulerum, said lever also having a bent pa-rt forming a catch which engages in .the Eother opening and Ia terminal part ,eXtendin Y normal-ly along the outside of said barrel eyond said `catch:substantially as set forth.
